Cossette no Shouzou, Tenshi no Tamago Recommendations

Two surreal concepts, transport us into dark worlds that hide a relationship that develops over time. Everything started because an object that is appreciated by the protagonist (A drink in Cossete, An egg in Tenshi), which keeps within himself, his own hope to change what is their world.

Very similar atmosphere and gothic imagery, revolving around a mysterious girl and her circumstances. Both try to intrigue the viewer by uncovering the worlds and characters mysteries, with Cosette being more on the nose and Tenshi no Tamago being more symbolic. Both have good, eerie soundtracks that fit the mood of the stories very well.
